Integrative differential pressure type gas-liquid two-phase flow wellhead monitoring device

Abstract

The invention relates to the technical field of oil production engineering, and belongs to an integrated differential pressure type gas-liquid two-phase flow wellhead monitoring device. The problem that the existing technology cannot synchronously measure gas-liquid two-phase flow is solved, the flow conversion problems under the working condition and the standard condition are solved, and the length of a metering device is shortened. The device includes a flange (1), a shunting impact homogenizer (2), a nut (3), a bolt (4), a static pressure sensor (5), a temperature sensor (6), a static pressure device (7), a moisture content sensor (8), an e-press (9), a differential pressure flowmeter sensor (10), an anti-venturi measuring chamber (11), a homogenizer slim tube (12), a lifting weir (13), an upper standby cap (14), a sleeve (15), a water content radio frequency antenna module (16) and a lower standby cap (17). The device is simple in structure and convenient to operate, products arehigh in cost performance ratio, and the measurement accuracy meets the requirement of gas well production.

Description

technical field [0001] The invention relates to the technical field of oil production engineering, and belongs to an integrated differential pressure gas-liquid two-phase flow wellhead monitoring device. Background technique [0002] The instantaneous gas and water production of a normal gas well is relatively stable, but once the gas well accumulates liquid, the instantaneous gas and water production will fluctuate greatly. Therefore, the instantaneous production of the gas well can reflect the change of the working condition of the gas well in time. At present, in the production process of gas wells, there is a gas-liquid two-phase flowmeter in the metering device, such as the product described in the patent No. "CN201610089484.0", which requires two flowmeters to realize the phase separation flow Metering, the gas-liquid two-phase flow cannot be measured simultaneously, and the flow conversion between the working condition and the standard condition cannot be realized. ...
